Dotta 0eacad0d0c fix: refresh preserved harness receipt facts without copying archives (#20322)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Volume-free deployment must preserve historical controller files
before removing the old disk.
> - A WEB preservation receipt binds an archive and source files to the
selected session and database facts.
> - Later metadata changes can make those facts stale while the
preserved files and archive remain unchanged.
> - The existing owner refuses every stale receipt, so preservation
cannot converge.
> - This pull request refreshes only facts freshness after it verifies
the same source bytes, checkpoints and archive.
> - Existing locks and an old-receipt digest comparison prevent a
concurrent replacement from being overwritten.

## Linked Issues or Issue Description

Refs #19814 for WEB evidence preservation without settling remote
recovery. Refs #19832 for bounded larger inventories. Related harness
receipt PRs were searched; no existing change provides this guarded
refresh.

**What happened?**

A valid WEB preservation receipt becomes stale after later run metadata
changes. Its original-volume owner refuses another preservation attempt
because an invalid receipt already exists. This leaves an eligibility
blocker even when the source and saved archive are unchanged.

**Expected behavior**

The original-volume owner can refresh stale facts only after it proves
every other persisted binding unchanged. It retains the prior receipt
and remote recovery state.

**Steps to reproduce**

1. Preserve a settled session's WEB files and controller evidence.
2. Add later run metadata so its database facts digest changes.
3. Preserve the same scope again. The previous implementation refuses at
the existing-receipt check.

**Paperclip version or commit**

The failure was reproduced on master
`12523fb677585fcd6da929f868014514a4e96e87`. This branch includes master
`1b7fe33432016b3b27ccdfbf7b8944da4b40726d`.

**Deployment mode**

Managed Linux server with PostgreSQL and durable object storage.

## What Changed

- Reuse the exact prior archive for existing WEB receipts. Recheck
current source bytes, controller history, checkpoint material and
archive bindings. Read back ciphertext and verify its size and hash.
- Permit only database/local-observation freshness changes. Selected
session, source run, controller, archive, WEB entries, and assets must
still match the prior proof. Local inode and timestamp observations may
change across attempts; preserved bytes, paths and modes must match.
- Recheck current facts and source files under the existing finalizer,
task and run fences. Accept a matching concurrent winner or require the
exact previous receipt digest before replacement.
- Retain the prior database and local facts digests, witness
fingerprint, observation time and receipt digest in the same
company-scoped activity transaction. Require those four fields to
reconstruct the exact prior proof from unchanged current bindings before
replacement. Normal audit redaction stays enabled.
- Preserve current-key checks and archive reads on ordinary idempotent
calls. Keep active-source, changed-evidence and cancellation refusals.
- Document the refresh contract. No schema, saved-run format or public
API change.

## Verification

- Genuine RED: the new real PostgreSQL/encrypted-archive case failed at
the old previous-invalid gate.
- Before the audit review follow-up, the full local owner suite passed
**94/94 integration cases in 50.01 seconds**. It covers same-archive
refresh with no PUT, audit history, current-key failures, unreadable
archives, cancellation, changed files, replaced volume, active sources,
matching concurrent winners and conflicting receipt replacement.
- The cases also cover a source becoming active during an idempotent
readback. Earlier 91- and 93-case runs preceded these final review
guards and are not the final result.
- Server typecheck, module boundaries and diff checks passed on the
final production/test bytes before the clean master merge. Required CI
supplies final-head breadth. Four narrow post-merge
refresh/current-key/idempotent regressions passed in 5.70 seconds on
`82e270f29fff98442c4184b96082f72f18a88721`.
- The fixtures use a real disposable PostgreSQL database and actual
local encrypted archives/storage. Controlled faults affect the stated
storage or concurrency boundary. They do not prove a hosted refresh or
archive plaintext cold restore.
- The existing integration file now exceeds 1,000 lines. Keeping these
cases with its private original-volume, controller, archive and
PostgreSQL fixture avoids duplicating that setup.
- Initial worktree preflight stalled on the global package-manager
wrapper. Preflight completed with the existing pinned toolchain. No
setup failure is counted as a product test pass.
- Review found that activity redaction could change a full prior-receipt
copy. A new regression enabled the real username censor and reproduced
that mismatch. The fix stores only the four changed scalar fields and
their original proof digest; a prepublication canonical reconstruction
guard rejects dropped or unknown fields.
- On the audit follow-up, 16 affected real PostgreSQL cases passed in
11.98 seconds; 80 unchanged cases were intentionally skipped. They
include real redaction with a username-containing WEB path,
reconstruction across two refreshes, unknown prior fields, CAS, active
sources, current-key failures, unavailable archives and cancellation.
Final server typecheck and boundaries passed. This was an intermediate
revision; the final-head results appear below.
- A second review found that comparing old inode/timestamp observations
also broke ordinary valid retries. Three real cases reproduced
valid-receipt touch/inode failures and stale-facts touch failure. The
fix permits metadata freshness changes across attempts while keeping
exact byte/path/mode/checkpoint/archive coverage and the existing locked
within-attempt metadata fence.
- Final local owner suite on the metadata follow-up: **102/102
integration cases passed in 44.04 seconds**, including valid
touch/new-inode retries, stale refresh with the same archive and no PUT,
four-scalar audit reconstruction, changed bytes/mode/entries, and a
touch during archive readback that must refuse. Server typecheck, module
boundaries and diff checks passed. The final-head CI and review results
appear below.
- Final head `c81475c927d0862dcb8d2c2356dc41ab4a27e63f`: [PR workflow
attempt
5](https://github.com/paperclipai/paperclip/actions/runs/42667287803/attempts/5)
completed successfully at 19:24:28 UTC on 2026-11-09. All 51 jobs are
accounted for: 49 passed and 2 were skipped. The actual [final ci /
verify](https://github.com/paperclipai/paperclip/actions/runs/42667287803/job/129382061558)
and [E2E
aggregate](https://github.com/paperclipai/paperclip/actions/runs/42667287803/job/129381486342)
passed. Typecheck, build and the selected test lanes passed. The
exact-head rollup is successful with no pending or failed checks.
- Attempt 5 resolved both trusted workflows to
`3a2f71db31aa99633610dc241f55f34ac65124de`, after #20339 merged. Its
routing gate passed and real jobs started. This verifies successful
startup and completion of this rerun; it does not exercise the
empty-runner fallback because routing succeeded.
- Earlier CI failures on `82e270f29fff98442c4184b96082f72f18a88721` and
attempts 1–4 of this final-head workflow remain nonpasses. Attempt 1 had
interrupted leaf jobs and failed aggregates. Attempts 2 and 3 ended in
workflow failure without a final verify job. Attempt 4 failed startup
with zero jobs and empty-runner errors. Those failures are not counted
as passes or labeled unrelated.

- Hosted application to an actual stale scope remains pending normal
release delivery.

## Risks

- Refresh must not bless different preservation evidence. The
unchanged-binding checks, fresh file and checkpoint proof, exact archive
reuse, source capability and locked receipt comparison remain mandatory.
- A fresh capability has a new witness fingerprint and expiry. The audit
retains the old fingerprint, database/local facts digests and
observation time. All unchanged proof bindings remain on the current
receipt. Their canonical reconstruction must match the old digest. The
new capability is validated at entry and publication.
- Readback verifies ciphertext size/hash and current-key checkpoint
material. This change does not claim a new archive GCM/plaintext
restore.
- Archive identity and rows remain unchanged, so retention ownership
does not change. Failed refreshes retain the previous receipt, original
files and unresolved remote recovery obligations.
- Older receipt shapes are not rewritten automatically. Normal
validation and named preservation refusals remain in force.
